Moscow concert attack: Russia links gunmen to Ukraine

More bodies of those killed in the attack on a Moscow concert hall have been found beneath the rubble of the building.

President Putin claims the attackers were trying to flee Russia over the border to Ukraine. At least 133 people were killed and 140 injured after gunmen opened fire at the crowd in the packed venue.
